INGEPAC EF-VR

INGEPAC™ EF VR allows voltage regulation in power transformers with tap changers, keeping the output voltage of the transformers steady and sending the signals to raise or lower taps to the tap changer.

INGEPAC™ EF VR is suitable to operate independently or in parallel configurations, up to 5 transformers connected to the same busbar. The communication between the voltage regulators will be carried out through IEC 61850 GOOSE messages.

In order to monitor the status of the transformer and control its useful life, INGEPAC™ EF VR allows the monitoring of oil temperature, which can be collected either through RTD inputs or through mA input.

INGEPAC DA-PT (Feeder protection relays)

INGEPAC™ DA PT are digital multifunctional protection relays, suitable as main protection of feeders or small motors, due to 8 analog channels (4 currents and 4 voltages).

Optionally, INGEPAC™ DA PT includes arc flash detection function that allows to perform general trip if the activation of any available light sensors is detected. Available up to 4 INGEPAC™ LSD light sensors. Tripping can be caused by light detection or light detection monitored by a high-speed overcurrent.

INGEPAC™ DA PT provides comprehensive and detailed information by means of its monitoring and events recording capabilities, these being fundamental elements in an electrical grid’s improvement process.
